Fuel cell apparatus

摘要

A fuel cell apparatus includes a stack (400) generating electricity by an anode gas and a cathode gas, a heat Insulating layer (800) covering an outside of the stack (400), a cathode gas flow passage (500), an exhaust gas flow passage (600), a housing (200) facing the stack (400), accommodating the stack (400), the heat insulating layer (800), the cathode gas flow passage (500), and the exhaust gas flow passage (600), and including a side wall (200s, 212, 222, 232) and a bottom wall (200b, 213, 223, 233), wherein at least one of the side wall (200s, 212, 222, 232) and the bottom wall (200b, 213, 223, 233) in a cross section taken along a vertical direction (H) of the housing (200) or a horizontal direction of the housing (200) is formed to be curved outwardly so that an intermediate area (200c, 212c, 222c, 232c, 200bc) at at least one of the side wall (200s, 212, 222, 232) and the bottom wall (200b, 213, 223, 233) is positioned further away from the stack (400) than both ends of at least one of the side wall (200s, 212, 222, 232) and the bottom wall (200b, 213, 223, 233).
